One-piece plastic clothe peg of the type comprising two branches (2,2', 3,3') fast one with respect to the other via a thinned bridging (4) between the middle parts (1, 1') in opposite relationship to the two branches (2,2', 3,3') with interposition of an elastic element between the rear parts of the branches (3, 3') which element is constituted by resting the two ends (6, 6') of flaps (5, 5') one over the other, after bending backwards (11, 11') thereof, characterized in that said flaps (5, 5') are produced by partial cutting (8, 8') according to a U-configuration base of each back branch (3, 3').

Description

La présente invention concerne une pince à linge en matière plastique d'une seule pièce.The present invention relates to a plastic clothespin in one piece.

Il est connu de réaliser des pinces à linge en matière plastique d'une seule pièce.It is known to make plastic clothespins in one piece.

Le FR-1 158 736 décrit une épingle à linge en polyéthylène, en une seule pièce comportant des languettes élastiques sur les faces internes des leviers. Dans ce type d'épingle, les languettes sont montées avec une courbure opposée à celle de leur position d'utilisation.FR-1 158 736 describes a polyethylene clothespin, in one piece having elastic tabs on the internal faces of the levers. In this type of pin, the tongues are mounted with a curvature opposite to that of their position of use.

Ce mode de réalisation suppose d'utiliser un matériau très élastique, ce qui peut nuire à la rigidité de l'ensemble. D'autre part, le moulage de telles épingles est une opération relativement complexe compte tenu de la forme très découpée de ces pièces.This embodiment assumes the use of a very elastic material, which can affect the rigidity of the assembly. On the other hand, the molding of such pins is a relatively complex operation given the very cut shape of these parts.

L'invention permet de remédier à ces inconvénients en proposant une pince à linge en matière plastique d'une seule pièce du type comportant deux branches solidaires l'une de l'autre par un pontage aminci entre les parties médianes en vis-à-vis des deux branches avec un élément élastique, interposé entre les parties arrière des branches et constitué par la mise en appui l'une sur l'autre, après rabat vers l'arrière, des deux extrémités de languettes caractérisée en ce que lesdites languettes sont réalisées par découpe partielle en « U sur le fond de chacune des branches arrière.The invention makes it possible to remedy these drawbacks by proposing a plastic clothespin of a single piece of the type comprising two branches integral with one another by a thinned-out bridging between the median parts opposite. of the two branches with an elastic element, interposed between the rear parts of the branches and formed by pressing one against the other, after flap towards the rear, of the two tongue ends characterized in that the said tongues are produced by partial cut in "U" on the bottom of each of the rear branches.

Selon une autre caractéristique de l'invention, les deux branches ont une section en « U », et la partie non découpée du fond définissant la zone charnière de pliage élastique des languettes est située du côté arrière des branches.According to another characteristic of the invention, the two branches have a “ U ” section, and the uncut portion of the bottom defining the hinge zone for elastic folding of the tongues is located on the rear side of the branches.

Selon une autre caractéristique de l'invention, la longueur des languettes et la position des charnières sont telles que la mise en appui de l'extrémité libre des languettes s'opère lorsque celles-ci subissent un rabat vers l'arrière d'environ 130° par rapport au plan du fond de chaque branche.According to another characteristic of the invention, the length of the tongues and the position of the hinges are such that the free end of the tongues presses when they undergo a flap towards the rear of approximately 130 ° relative to the bottom plane of each branch.

Selon une autre caractéristique de l'invention, à l'extrémité arrière des branches, une cloison verticale relie les deux ailes de la section en « U » des branches. Cette cloison est prévue pour le placement du pouce et de l'index lors de l'utilisation de la pince.According to another characteristic of the invention, at the rear end of the branches, a vertical partition connects the two wings of the “U” section of the branches. This partition is intended for the placement of the thumb and forefinger when using the pliers.

Selon encore une autre caractéristique, les cloisons verticales latérales des sections en « U » possèdent, dans la partie arrière des branches, une ou plusieurs perforations cylindriques, tandis que la partie avant des branches possède, sur les flancs extérieurs des cloisons verticales des sections en « U », des proéminences latérales cylindriques.According to yet another characteristic, the lateral vertical partitions of the U-shaped sections have, in the rear part of the branches, one or more cylindrical perforations, while the front part of the branches has, on the outer flanks, vertical partitions of the sections "U", lateral cylindrical prominences.

L'épaisseur et le diamètre de ces proéminences sont tels qu'elles peuvent s'enfoncer dans les perforations ménagées sur l'arrière des branches d'une autre pince du même type constituant ainsi des éléments de jeu de construction.The thickness and the diameter of these prominences are such that they can sink into the perforations formed on the rear of the branches of another clamp of the same type thus constituting construction play elements.

L'invention sera mieux comprise à la lecture de la description qui va suivre et les dessins annexés qui représentent :

  • Figure 1 Une vue en perspective de l'ensemble.
  • Figure 2 Une vue de détail d'une branche arrière avec le pliage de la languette.
  • Figure 3 Une vue de positionnement de l'index et du pouce sur chacune des branches arrière de la pince à linge.
The invention will be better understood on reading the description which follows and the attached drawings which represent:
  • Figure 1 A perspective view of the assembly.
  • Figure 2 A detail view of a rear branch with the folding of the tongue.
  • Figure 3 A positioning view of the index finger and thumb on each of the rear legs of the clothespin.

La pince à linge telle que représentée figure 1 comporte :The clothespin as shown in Figure 1 includes:

Deux branches 2,2', 3,3' solidaires l'une de l'autre par un pontage aminci 4 de même matière entre les parties médianes 1,1' en vis-à-vis des deux branches 2,2', 3,3', avec un élément élastique 5,5' interposé entre les parties arrière des branches. Ladite pince à linge est réalisée en une matière plastique du type polypropylène, et l'élément élastique est constitué par la mise en appui l'une sur l'autre après rabat 11,11' vers l'arrière des deux extrémités 6,6' des languettes 5,5' sur le fond de chacune des branches arrière 3,3'.Two branches 2.2 ′, 3.3 ′ secured to one another by a thinned bridging 4 of the same material between the middle parts 1.1 ′ facing the two branches 2.2 ′, 3 , 3 ', with an elastic element 5.5' interposed between the rear parts of the branches. Said clothespin is made of a plastic material of the polypropylene type, and the elastic element is constituted by the abutment one on the other after flap 11,11 'towards the rear of the two ends 6,6' tabs 5.5 'on the bottom of each of the rear legs 3.3'.

De plus, la pince à linge représentée comporte :In addition, the clothespin shown includes:

Des branches 3,3' avec une section en « U » 12,12' dont le fond comporte une découpe partielle 8,8' en « U dont la partie non découpée 7,7', définissant la zone charnière de pliage élastique des languettes 5,5' est située du côté arrière des branches 3,3'.Branches 3.3 ′ with a “U” section 12.12 ′ whose bottom has a partial cutout 8.8 ′ in a “U” with the non-cut part 7.7 ′, defining the hinge zone for elastic folding of the tongues 5.5 'is located on the rear side of the 3.3' branches.

De plus, dans un mode de réalisation préféré de la pince à linge selon l'invention, la longueur des éléments élastiques 5,5' et la position des charnières 7,7' (ou lignes de rabat) sont telles que la mise en appui de l'extrémité libre 6,6' des languettes 5,5' s'opère lorsque celles-ci subissent un rabat 11,11' d'environ 130°.In addition, in a preferred embodiment of the clothespin according to the invention, the length of the elastic elements 5.5 'and the position of the hinges 7.7' (or flap lines) are such that the support from the free end 6.6 ′ of the tongues 5.5 ′ operates when these undergo a flap 11.11 ′ of approximately 130 °.

La présente invention a pour but d'améliorer la fabrication dans le sens où la pièce sort du moule métallique d'une seule pièce.The present invention aims to improve manufacturing in the sense that the part comes out of the metal mold in one piece.

L'objet fabriqué par injection comporte des languettes pré-découpées par contact des plans .de joint du moule métallique sur trois côtés de ces dites languettes.The object manufactured by injection comprises pre-cut tabs by contact of the metal mold joint planes on three sides of these said tabs.

La mise en position définitive des languettes se fait de la façon suivante :The final positioning of the tabs is done as follows:

La pièce est éjectée du moule, réceptionnée sur une bande transporteuse, orientée, engagée dans un couloir où elle est positionnée à plat, avance pas à pas jusqu'à un poste où des tiges poussoirs poussent les languettes pour les mettre en contact d'appui à leur extrémité par retournement d'environ 130°C. Cette opération ayant lieu pendant la période de pré-stabilisation de la pièce.The part is ejected from the mold, received on a conveyor belt, oriented, engaged in a corridor where it is positioned flat, advances step by step to a station where push rods push the tabs to bring them into contact with support at their end by inversion of approximately 130 ° C. This operation takes place during the pre-stabilization period of the part.

Il peut être prévu ensuite une mise en carte, un étiquetage.Provision may then be made for carding and labeling.

La pince à linge de l'invention telle que représentée figures 2 et 3 comporte :The clothespin of the invention as shown in Figures 2 and 3 includes:

A l'extrémité des branches arrière 3,3', une cloison verticale 14,14' reliant les deux ailes et le fond de la section en « U " 12,12' des branches.At the end of the rear branches 3.3 ′, a vertical partition 14.14 ′ connecting the two wings and the bottom of the “U ” section 12.12 ′ of the branches.

Cette cloison sert d'appui au pouce et à l'index et évite à la pince de glisser vers l'avant en particulier lorsque l'utilisateur a les mains humides.This partition serves as a support for the thumb and forefinger and prevents the clamp from sliding forward especially when the user has wet hands of.

De plus, la pince à linge représentée comporte sur les cloisons verticales latérales de la partie arrière des branches en « U " 3,3' une ou plusieurs perforations 10,10' cylindriques, la partie avant des branches 2,2' possédant à son extrémité, sur les flancs extérieurs des cloisons verticales, des proéminences 9,9' cylindriques, l'épaisseur et le diamètre de ces .proéminences étant tels qu'elles peuvent s'enfoncer dans des perforations cylindriques 10,10' ménagées sur l'arrière d'une autre pince du même type.In addition, the clothespin shown has on the vertical side walls of the rear part of the branches in "U " 3.3 'one or more cylindrical perforations 10,10', the front part of the branches 2,2 'having at its end, on the outer sides of the vertical partitions, cylindrical protrusions 9.9 ′, the thickness and diameter of these protrusions being such that they can sink into cylindrical perforations 10.10 ′ formed on the rear another clamp of the same type.

L'utilisation de ce type de pince à linge comme jeu de construction, par possibilité d'imbrication des pinces les unes dans les autres, suscite une autre dimension au côté attractif qu'ont traditionnellement les pinces à linge sur les enfants.The use of this type of clothespin as a construction toy, by the possibility of nesting the tongs into one another, gives another dimension to the attractive side that the clothespins have traditionally had on children.
